You’ll need to hold frequent dialogues in order to become familiar with the core wounding discount doxycycline 200 mg mastercard antibiotics for persistent uti, coping strategies and needs of your inner child. However, the real issue is how you deal with your mind on a moment-to-moment basis during a stressful event. You can either bring your attention to the breath or intentionally breathe in a relaxed manner. This, initially, may be all that you can do in the heat of a really stressful moment. However, as you become more experienced in the practice of mindfulness and more familiar with the inner child and its underlying feelings and needs, you’ll be able to apply some of the other techniques that you’ve learned. Try one or more of the following approaches during a stressful moment, but remember that they’ll all be much more effective and easier to do if you’re regularly practicing, mindfulness, relaxed breathing, and inner-child dialoguing: • Bring your attention to the physical sensations and rest in the body knowing that you’re directly experiencing how the inner child feels. Mindfulness of your thought process is a wonderful way to step out of the storyline and bring awareness to how your mind works. Remember, the story that Larry told himself: I bought the suit and now I’m terrible and will be penniless. Mindfulness of the Inner Child: Putting It All Together • 231 It was Larry’s story that was stressful, not the fact that he bought a suit. Once you’ve been practicing mindfulness and inner-child dialogue for some time and have truly begun to understand that the stressful mental states that you’re experiencing are fabrications of the mind, 232 • Mindfulness Medication invented stories based on your childhood belief system, you can be present in any given moment in a very freeing way. The qualities of any internal or external stressful sensation or event that you experience are all creations of your mind. Stress is produced by your reaction in the moment, as you gauge everything you experience according to your belief system. When you experience something that you’re interpreting as stressful, say to yourself: • This is a fabrication, a story of the mind, and I choose not to believe it. I will just rest in the knowledge that the mental state that I’m experiencing is an illusion of the mind. As the last important step in your integrated practice, I want you to consider how you act toward others. The question is whether this is a dominant motivation in how you behave, or whether a more universal, compassionate, connected perspective dictates your behaviour. As you start to see the illusory nature of how the mind constructs its suffering, based on the conditioned reality of the inner child, there’s less to defend and your heart can open. Some Imight define happiness as having more things, but for me, it’s being able to be present for whatever my mind poses to me, without automatically and unconsciously reacting in a fearful, angry or anxious way. I want to be present from an openness of heart that doesn’t need to defend my ego or my inner child. I have explored many different spiritual and psychological traditions in my own personal quest to find greater happiness. I have found that the ability to have an inner-child dialogue, as a way to understand the core motivation for how my mind works, along with the ability to hold the experience mindfully, to be complementary and transformative techniques. I encourage you to view each moment of awareness, whether it’s perceived to be good or bad, as a gift. Every moment of mindfulness brings you a step closer to freedom from stress and suffering. The goal is to bring awareness to the inner child 233 234 • Mindfulness Medication and hold it with the compassion and spaciousness of mindfulness. Our minds are capable of being angry, sad or happy and we identify with and then tend to become those emotional and mental states. One leads to stress and suffering and the other to an open acceptance, without the ownership and grief, of whatever is currently happening. I believe that it’s because we’re not aware that we can choose to operate from a different perspective. We haven’t learned that we can use mindfulness and inner-child dialogue to deal with the unconscious, conditioned, coping strategies of the wounded inner child. Freedom from stress ultimately comes from observing that suffering is really a mental construction, and that means you’re free to change it. I have tried to outline some practical approaches to lasting stress reduction so that, at the end of the day, you have some excellent techniques to work with.

The high porosity of the system means that it dissolves instantaneously on the tongue and does not require water to aid swallowing cheap doxycycline 100 mg amex antibiotic resistance npr. A number of products are currently available which use the Zydis technology including Dimetapp Quick Dissolving Tablets, Feldene Melt and Pepdine. However, it is important to note that the system does not actually facilitate oral transmucosal delivery per se, rather it allows rapid release of the drug in the mouth. The drug is then washed down with the saliva for subsequent absorption in the gastrointestinal tract. The convenience and acceptability of a Zydis formulation make it particularly suitable for patients who find it difficult or inconvenient to swallow solid dosage forms. In trials, up to 90% of patients expressed a preference for taking the Zydis formulation compared with a conventional tablet. Important features for drug delivery associated with these novel buccal patches include: 7. Multi-directional release The type of patch allows release of the drug moiety to the underlying mucosa (and thus the systemic circulation) and also to the saliva bathing the oral cavity (Figure 7. Drug released into the saliva may also be absorbed systemically through the mucus membranes of the oral cavity and/or remain locally. However, disadvantages associated with this approach include: • the drug becomes substantially diluted in the saliva; • substantial loss of the drug may occur when the saliva is swallowed; 182 Figure 7. Unidirectional release In this type of system, drug loss to the saliva can be decreased by using an impermeable backing layer (Figure 7. An additional advantage of these systems is that the effect of additives can be restricted to the site of application. However, this approach also means that the drug moiety is confined to the site of application, thus the available absorption area is quite small. Furthermore, presence of a backing layer can also decrease the flexibility of the dosage form leading to increased patient discomfort and reduced patient compliance. Drug release rate can be controlled by the use of: Matrix or drug-in-adhesive systems The drug is distributed throughout a polymer matrix. Such a system can be relatively easy to manufacture, the simplest case being when the drug is dispersed directly in a blend composed of, for example, a mixture of poly(acrylic acid) and elastomeric compounds such as poly(isobutylene) and poly(isoprene). Reservoir systems The reservoir patch has a similar bioadhesive component but pharmaceutical formulations containing certain excipients, such as penetration enhancers and enzyme inhibitors, can be placed in the center of the design. Matrix and reservoir systems, and their drug release profiles (firstorder, and square-root time order, respectively), have been discussed in detail in Chapters 3 and 4. However, patch size must always be considered with respect to patient comfort and acceptability and must not be too large so that these factors are compromised. Thus the size of adhesive patches is generally in the range 2–5 cm, with 10–15 cm being2 2 the upper limit. The principal mechanism for bioadhesion of oral patches appears to be physical entanglement of the adhesive polymer of the patch in the mucus glycoprotein chains, with secondary (electrostatic, hydrogen, hydrophobic) chemical bonding playing a minor role. Adhesive polymers used in oral patches include poly(hydroxyethylcellulose), poly (hydroxypropylcellulose), poly(sodium carboxymethylcellulose), poly(acrylic acid), poly(methacrylic acid), poly(vinylpyrrolidone) and poly (vinyl alcohol). The binding properties of a given polymer are affected by physicochemical properties such as its molecular weight, configuration, cross-linking density, charge and concentration. As well as initial tack properties, another important consideration is the duration of bioadhesion. The influence of viscosity on adhesion time depends on the type of polymer, for example poly(vinylpyrrolidone) affords an adhesion time which increases exponentially with viscosity grade. Poly(hydroxyethylcellulose) and poly(vinyl alcohol) also show increased adhesion times with increasing viscosity; however, the reverse is true for hydroxypropylcellulose. Regardless of the viscosity, increasing the amounts of polymer in the patch increases the adhesion time. Patches with backing layers that are permeable to water generally show shorter adhesion times than those with impermeable backing layers. This is due to the slower erosion of the hydrocolloid when one side of the patch is protected against water uptake. The limited surface area available for absorption often means that a2 penetration enhancer is necessary to ensure: • an effective dose can be delivered from a patch of reasonable size; • the range of transmucosal drug delivery candidates can be extended, for example, to include poorly absorbed moieties such as therapeutic peptides and proteins. Penetration enhancers are discussed extensively for the transdermal nasal route in Sections 8.
